Abstract (en)
[origin: EP0741332A1] A photosensitive resin composition suitable as a resist material against sandblasting for pattern-wise engraving of the surface of a body after photolithographic patterning, comprises: (a) a urethane compound having a (meth)acrylate group at the molecular end, which is obtained from a polyether or polyester compound having a hydroxy group at the molecular chain end, a diisocyanate compound and a (meth)acrylate compound having a hydroxy group; (b) an alkali-soluble polymeric compound having an acid value in the range from 50 to 250 mg KOH/g; and (c) a photopolymerization initiator.
